CONNECTER.

Application filed June 4, 1924, Serial No. 717,911. Renewed July 1,1925.

To all whom it may concern:

Be it known that 1, ROBERT E. JELLISON, a citizen of the United States, residing at New Auburn, in the county ofSibley and State of Minnesota,- have invented new and useful Improvements in Connectors, of which the following is a specification.

The objectof my said invention is the provision of a connecter susceptible oi'use to advantage ii -many relations and characterized by a capacity to be released .while fully loaded or-subjected to strong pull'and also chracterizedby the capacity of resisting release until it is operated in the manner to be-described by an operator.

Other objects and practical advantages of the'invention will be fully understood from the following description and claims when the same are read in connection with the drawings, accompanying and forming a part of this specification, in which Figure lis a detail side. elevation. of one of the side sections ofthe connector.

Figure 2 is an edge elevation of a connecter constructed in accordance with my invention.

Figure 3 is avertical sectionshowingthe connector as closed.

Figure 4 is a similar view showing the connector as open.

Figure 5 is a longitudinal. central section taken in; the plane indicated by the line 55 of Figure-4:.

Figure dis top plan view of the con necter,

Figures 7, 8, 9 and 10 are perspectives of elements comprised in the connecter and hereinafter referred to in detail.

Similar numerals of reference designate corresponding parts in allot the views of the drawings.

Among other elements my novel conu-ecter comprises an aperture housing, thehousiug in the embodiment illustrated including side sections 1 and 2, appropriately held t t-her as by boltsS and nuts 4 and'also including edge sections 5 and 6 in the latter of which is an opening 7. It will also be noticed that the side sections 1 and 2 are provided in their inner sides with recesses 8 of general angular configuration as appears in Figures 1 to 3. I would also have it understood that when desired the housing section 2 may be provided with a bracket 9 for the pivotal connection of a bail 10 in which is mounted a-nti tric on rol er, 11, adapted to be dis ,a cable. section posed in the loop of a piece of harnessor the like.

Disposed. and movable in the angular recesses 8 are the end portions v12 oi a transthe jaws 1-9 and 20 of my improvement,

the bolts referred to being arranged at oppositesides-of the inner ends of bifurcations 21 in. the housing sections 1 and2, and the jaws being adapted to be moved from the positions shown in Figure 3 to the positions shown in Figure 4, and vice versa. The jaws 19 and 20 are preferably shaped-as shown though they may be otherwise shaped in consonance with my invention withoutinvolving departure from the scope of the invention as claimed. i

Fix-ed to the aw 19 is an arm 21 relatively arrangedas illustrated, and interposed between; and connected to said arm 21 and the before mentioned transverse pin 18 is a retractile spring'22. The inner aortions of thejaws 19 and 20 are provided with apertures 23 in their inner portions, the said apertures 23 being of circular form to receive the circular portion 24 of a second transverse member, Figure 8, which transversemernber in addition to the circular portion 24: istprovided with angular end portions 25 which are disposed in the angular apertures 17 ofthe links Connected to the lirstmumed transverse member of the device, which member for identification is generally niunoered 39, is 31 which intends through and is ,inovable in the opening 7 and is do signed to be used by an operator in opening the connecter i. e, moving the jaws l9 and 20 and their appurtena .1065 from the positions shown in Figure. 8 to the positions shown in Figure l. When pull is exerted on the cable 31 in a direction away from the housing, the jaws 19 and 20 will be opened, the spring 22 will be expanded, and the member 30 will be moved in the recesses 8. Consequently, the spring 22 will be enabled to yieldingly retain the jaws 19 and 20 in theopen positions. When, however,

any device 32 such as a link of a chain or ring thereof to be engaged by the connecter is thrust in the direction indicated by arrow in Figure 4 against the connected portions of the jaws, the jaws and the links will be moved in the direction of the arrow until the transverse member reaches the upper arms of the recesses 8 whereupon the spring 22 will promptly contract and close the jaws upon as said device 32 which obviously may be of any description. I

By reference to Figure 3 in which device 32 is shown by way of example, it will be manifest that whenthe jaws are snapped closed, the device 82 will be confined in the jaws, and any pull exerted on the device 32 in the direction opposite to that indicated by arrow in Figure l will only serve to more strongly hold the jaws in closed state, with the result that there is no liability whatever of a device held in the ,connecter being casually released. j 7

It will be apparent from the foregoing that my novel connector may be employed to advantage in very many relations, and it will also be apparent that the connecter is compact and strong in construction and is therefore well adapted to withstand rough usage to which connectors are ordinarily subjected in heavy work.

I have specifically described the preferred embodiment of my invention in order to imparta full, clear and exact understanding of the said embodiment. I do not desire, however, to be understood as confining myself to the specific construction and relative arrangement of elements as described inasmuch as in the practice of my invention various changes may be made within the scope of my appended claims which define my invention.

Having described my invention, what I claim and desire to secure by Letters-Patent, is

1. A connecter comprising a housing, swinging jaws in and connected to said housing, swinging means in the housing and connected to the jaws and movable endwise coincident to the opening and closing of the jaws, a retractile spring interposed between and connected to said swinging means and one of the jaws, and two-operating means 'arried by the housing and swinging means for yieldingly retaining the jaws in open positions when the said spring is tensioned.

2. A connector swinging jaws in and connected to said comprising a housing,

housing, swinging means in the housing and connected to the jaws and movableendwise coincident to the opening and closing ofthe jaws, a retractile spring interposed between and connected to said swinging means and one of the jaws, and co-operating means carried by thehousing and swinging means for yicldingly retaining the. jaws in open positions when the said spring is tensioned; the housing being provided with an opening, and a cable being extended through said opening and connected with said swing ing and endwise movable means. 1 A connector comprising a housing having opposite sections and angular recesses in the inner sides of said sections, swinging jaws in and connected to the housing, swinging and endwise movable means connected to the jaws and having a transverse member with ends disposed and movable in said recesses, and a retractile spring interposed between one of the jaws and the said swinging portions.

4. A connecter comprising a housing having sections with bifurcated ends and with angular recesses in their inner sides, swinging jaws pivoted in the housing at opposite sides of the inner ends of said bifurcations, one of the jaws having an inwardly extending arm, links connected to the inner arms of the jaws and arranged to swing and move endwise, a retractile spring connecting said links and the arm on one jaw, and a transverse member interposedbetween and con nected to said links and having end portions disposed and movable in said angular recesses of the housing sections.

5. A connecter comprising a housing having opposite sections with end bifurcations, arms with angular recesses in their inner sides, j aws pivoted in said housing at opposite sides of the innerportions of said bifurcation, one of the jaws having an arm, a

transverse member extending through and pivoted in lapped portions of the jaws and having angular apertures receiving the angular ends of said transverse member, and a second transverse member having ends movable in said angular recesses and also having portions of angular cross-section disposed in angular apertures of the links, and a retractile spring interposed between and connected to the arm on one jaw and the said links.

In testimony whereof afiix my signature.
